Known repair windows
What GranTurismo owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.

Cost to keep
What it costs to own, by how long you keep it
Scheduled servicing only, from a brand-new GranTurismo at 12,000 miles a year. Insurance, fuel, tires and depreciation are yours to add - this is the part the shop charges you for.
| You keep it | Odometer | Servicing | Per month |
|---|---|---|---|
| 1 year | 12,000 mi | $0 | $0 |
| 3 years | 36,000 mi | $3,100 | $86 |
| 5 years | 60,000 mi | $11,000 | $183 |
| 7 years | 84,000 mi | $16,150 | $192 |
| 10 years | 120,000 mi | $24,900 | $208 |
| 15 years | 180,000 mi | $38,150 | $212 |
Per-month can dip as the horizon lengthens - a major service lands in one year and then averages out across all the months after it. The left column is what you actually spend.
Beyond the schedule, the first big-ticket item this GranTurismo is known for is Turbocharger / wastegate actuator ($2,500-$5,000). It is a range, not a certainty - but it is the number to have in your head at the dealership.
Operator notes
New (2023+) generation, Nettuno 3.0L twin-turbo V6 with pre-chamber combustion and dual (port + direct) injection that limits GDI carbon buildup. Timing CHAIN. Annual or ~12,500 mi service; spark plugs ~3 yr, belts/air filters ~4 yr. A GranTurismo Folgore trim is a tri-motor 800V EV (no oil, separate BEV schedule). Requires premium full-synthetic oil.
When the smart money sells
Keeping it yourself, there is no cutoff - the table above runs to fifteen years. On fleet math, where a car has to keep earning, a gas GranTurismo retires around 95,000 miles. Carlyle's garage tracks this per car, against your actual odometer.
Cost ranges are typical US independent-shop estimates and vary by region and condition. Modeling, not mechanic advice - always confirm against your car's service records.
